Question

Sinplifica estos sistemas de ecuaciones lineales:
2(x+4)+2(y - 3)=12
4(2x - 3)-2(y +1)=6

Answer 1

Respuesta:

2(x+4)+2(y - 3)=12

2x + 8 + 2y -6 = 12

2x + 2y +2 = 12

2x + 2y = 10

2(x + y) = 10

x + y = 5

4(2x - 3)-2(y +1)=6

8x - 12 -2y -2 = 6

8x - 2y -14 = 6

8x - 2y = 20

2(4x - y) = 20

4x - y = 10
